Millions of learners on platforms like edX and Coursera are generating terabytes of data tracking their activity in real time. Online learning platforms capture extraordinarily detailed records of student behavior, and now the challenge for researchers is to explore how these new datasets can be used to advance the science of learning.

In this edX co-sponsored talk Justin Reich — educational researcher, co-founder of EdTechTeacher, and Berkman Fellow — examines current trends and future directions in research into online learning in large-scale settings.
